FIRE-ALARM MECHANISM.

SPECIFICATION forming part of Letters Patent No. 750,012, dated January19, 1904.

Application led April 27, 1903. Serial No. 154,549. (No model.)

T all whom t may concern:

Be it known that I, LEoNIDAs G. WOOLLEY, residing at Kenton, in thecounty of Hardin and State of Ohio, have invented certain new and usefulImprovements in-Fire-Alarm Mechanisms, of which the following is aspecifica- This invention relates to that class of firealarm mechanismsin which the signal-setting and striker-operating mechanism is set inmotion by alternating magneto-currents, and my invention in its genericnature comprehends a novel construction of recording andstriker-operating mechanisms, including a series of number-wheels, onefor each iire district or circuit, each of which servesfto set adistinct individual signal and .strike an alarm.

The invention in its more complete nature includes a suitable drivemechanism for operating the number-wheels, the striker devices, and thesignal-setting mechanisms, together with devices for bringing eachsignal-setting and striker-operating mechanism into operative connectionwith the number-wheel and means for cutting out the remainingsignal-setting mechanisms, whereby but one alarm can be turned in at onetime, and thereby prevent any interference of the alarm-signals. Inother words, as soon as an alarmfrom one box is turned in its signalmechanism is set and at the same time every other boX in the system iscut out, so that a second alarm cannot be turned at the same orany otherbox during the striking of the first alarm.

Another essential feature of my present invention lies in the novelcorrelation of the starting mechanisms with the drive mechanism wherebythe alarm will be sounded a plurality of times before the drivemechanism will operate to return the parts to their normal orinoperative positions.

In its more subordinate features my inven- -tion consists in a. numberof structural combinations and detail arrangement of parts, all of whichwill be hereinafter fully described, and particularly pointed out in theappended claims, reference being had to the accompanying drawings, inwhich- 1 positionsthe direction of the arrow 1.

l circuitV cut out.

Figure 1 is a top plan view of my invention arranged for tenfire-districts, the parts being in their normal or inoperativepositions. Fig. 2 is a cross-section thereof, taken on the line 2 2 ofFig. 1 and looking in the direction of the arrow 1, the vparts being intheir normal taken on the line 3 3 of Fig. 1 and looking in Fig, 5 is across-section taken practically. on the line 5 5 of Fig. 1 looking inthe direction of the arrow 2, the parts being in their normal positions.Fig. 6 is a similar view, the parts being in their operative positions.Fig. 7 is a detail perspective view of one of the ratchetdisks, togetherwith its bearing, and showing the means for returning the disk to itsnormal position after the alarm has been sounded.

Fig. 8 is asimilar view of one of the numberings, in which like numeralsand letters of ref erence indicate like parts in all of the figures, 10designates a suitable base, upon which is mounted a drive andcontrolling mechanism, indicated generally by A, and which consists of adrive-motor, including a casing 11, in which is secured a stout fiatcoil-spring 12 of the clock-spring type fastened at oneend to themotor-casing and at the other end in the ordinary manner to the shaft13, running through side walls 1121 11D of the casing 11 and mounted toturn in suitable bearings in the Figs. 3 and 4 are similar viewsstandards 14 14C, which standards are secured to the base 10 and aresuitably braced by cross-bars 15 15a. (See Figs. 1 and 2.) Upon theupper cross-bar 15a is pivotally mounted a pawl 16, which engages theratchet 17, fixedlysecured to theshaft v13 and having teeth 17a. Securedto a bracket 18, mounted upon the standard 14 and held in engagementwith the pawl 16, is a fiat spring 19, which serves to hold the pawl 16in engagement with the ratchet-teeth 17 of the ratchet 17. 13b indicatesa square portion'of the shaft 13, to which may be litted any suitableturning-key, whereby the spring 12 of the drive-motor 11 may be wound.

2O indicates a bracket securely fastened to the standard 14, upon whichis pivoted a weight 21, having a heel portion 22 for a purpose presentlyto appear. The weight 21 has upon one face thereof an integrally-formedwing 23, which extends from about the pivot-point of the weight 21 tonear its outer end and with whicha stud 30, secured to the side wall 11of the casing 11, is adapted under predeter-v mined conditions toengage,while upon the oppositeface of the weight is a short stud 24, thepurpose of which will be hereinafter more fully explained. The bracket20 includes a pendent portion 25, in the lower endV of which is mounteda short shaft 26, carrying a crankarm 27 at one end and a latch 28 atthe other end, the said latch 28 being adapted under predeterminedconditions to engage with the heel portion 22 of the weight 21 to lioldsame in its elevated position, as shown in full lines in Fig. 2.

To the standard 14 is secured another bracket 29, to which is pivotedatrip, having a pendent portion 31 and a stud-engaging portion 32, withwhich the stud 33 on the side wall 11 of the casing 11 is adapted toengage in a manner hereinafter described.

Mounted in bearings on the standards 14 14 and carrying' a pinion 34,which meshes with a gear 34 on the motor-casing 11, is a long shaft 35,which carries a series of suitable spaced number-wheels 40, which willbe elearl y understood by reference to Figs. 1 and 5 of the drawings.

Mounted in bearings 36 37, one of which, 36, is secured directly to thebase 10 and the other formed upon one of the standards 54, is a shaft50, upon which is secured at suitable intervals a series of fingermembers 51, having a fiat spring portion 52, with which the lugs 53 onthe ratchet-disks 54 engage at predetermined times. To the end of theshaft 50 nearest the drive mechanism is secured an arm 55, having' acam-shaped portion 56 at its lower end and an enlargement 57 at itsbearing end into which is screwed a rod 58, which carries abalancing-weight 59, as shown in Figs. 1 and 2. Adjacent the arm 55 issecured a short crank 60, which is operatively connected to the crank 27by a rod 61, as shown, and with which a fiat springl 62 engages to holdthe same from undue vibration.

63 64 indicate bearings, in which is mounted another long shaft or rod65, carrying at one end an elongated arm 66, while between the standards14 14 and on one side of the motorcasing 11 is securely fastened to theshaft 65 a rigid linger 69 and on the other side a spring-finger 67 therigid finger 69 being adapted to bc engaged by the lug 24 on the weight21, while the lug 68 on the side wall of the motor-casing 11 normallyengages the spring-iinger 67 to hold the shaft 65 and its` arm 66 intheir normal positions.

To prevent the excessive speeding of the drive mechanism, andconsequently the alarm mechanism, l provide a governor device 70, whichincludes a gear 71, mounted upon the extension 35 of the shaft 35 andwhich imparts motion through gears 72 73 and pinions 74 75 to the shortshaft 76, carrying the governor proper and the stopping-disks. Thegovernor proper consists of a bracket 77, secured to the shaft 76torotate therewith, to which bracket is fulcrumed a pair of weightedmembers 78, held to their normal position by a spring 79, and whichmembers 78 include portions 8O for engaging with a collar 81, looselymounted upon the shaft 76 and carrying a Aliy-wheel 82. The iiy-wheel 82when the mechanism is in operation will frictionall y engage a disk 83on the shaft 84, and thereby prevent excessive speeding.

Referring now more particularly to Figs. 10 and 12, it will be seen thatupon the shaft 76 is secured a metallic disk and a collar 86, betweenwhich and the disk 85 is loosely mounted a second disk 87, having a rim88, with which is integrally formed a radial lug 88 for engaging the end66 of the arm 66 when the machine is at rest to prevent rotation of theshaft 76. To hold the disks 85 and 87 in tight frictional engagementwith each other, l1 provide a coil-spring 89, placed between the collar86 and the disk 87, as clearly shown in Fig. 10. y

Referring now more particularly to Figs. 1, 5, and 6, it will be seenthat I provide a series of magneto-motors, each of which consists of thepermanent steel magnets 90, between the pole-pieces 91l of which ismounted an armature 92 of any approved construction, which armature isadapted for oscillatory movement and is prevented from making' acomplete revolution by a pin 93 passing through an aperture 94 in theguard-plate 95. (See Fig. 5.) Upon one end of the armature-shaft 96 issecured an arm 97, to which is pivoted a pair of pawls 98 99, which passthrough a guide 10() on each standard 54 and are normally held inengagement with the ratchet-disks 54 by springs 98 98, secured each totheir respective pawls and to the bracket 8, mounted on the supplementalbase 9,which base 9 is in turn mounted upon the main base 10, which willbe clearly understood by reference to Figs. 5 and 6 of the drawings. Inthe outer end of the pro jecting portion 54 of the ratchet-wheel 54 ismounted a friction-roller 54", which when the disk 54 is in its normalposition engages with the flat portion 42 of the numberwheel straddlingpawls 42, as shown in Fig. 5, and

the'ratchet-disk shafts 54c pass through bearings 541 on the standards54e and the said shafts each carrying at the ends opposite theratchet-disks an arm 541, to which is pivotally secured a rod 54,carrying a weight 54 at its lower end. The weight 54h serves to turn theratchet-disk to its normal position when the pawls 98 99 are releasedtherefrom in the manner presently described.

The number-wheel-engaging pawl 42 has a n-shaped portion at its lowerend, in which is mounted afriction-roller 44 for engaging with theprojections 41 on the periphery of the number-wheels 40, and the pawl 42also includes at its lower end a pair of guide-legs 45, which straddlethe number-wheel and rest when the machine is in operation against theshaft 35, as is clearly shown in Fig. 6. The upper end of the pawl 42includes a bearing portion 46, by which each pawl 42 is pendentlymounted upon the rod 47, held in bearings 47 of the arms 48, which arms`48 are in turn mounted upon and secured to a second rod or ,shaft 47,movable in bearings 47 y (See Figs. 5 and 6.) To prevent lateralmovement of the pawls 42, I may, if desired, fix a collar (not shown) tothe rod 47 at each side of the bear? ings 46. To counterbalance theweight of the arms 48 and bearings 42, I provide balanceweights 49 onrods 49, screwed or otherwise fastened in projecting portions 49" on thebearing parts of the arms 48. l (See Fig. 1.)

Secured to one end of the horizontal portion 102 of the standards 102 isa board 103, upon which is pivoted a series of catches 104, each ofwhich includes a flat disk portion 104, to the rear face of which andprojecting through apertures 103 in the board 103 is a wing 104, asshown in Figs. 5 and 6. Integrally formed with the outer face of thedisk 104 is a downwardly-projecting portion 104, which is fulcrumed at104e to the bearing 1041. To the lower end of the board 103 and at rightangles thereto is secured a second board 103X for a purpose presently toappear. The other ends 102x of the horizontal portion 102 of thestandards 102 are formed with bearings 102y, upon which is mounted a rod105, carrying the indicating-drops 106, (shown in detail in Fig. 11,) byreference to which it will be seen the drops 106 consist of a bearingportion 106 and an arm 106, to which'is secured a number-carrying plate107. At the bearing end of the drop 106 is a slot 106, which cooperateswith the linger 106, adjustably secured to thebearing portion of thepawls 42. The outer face of theindicating-plate 107 is countersunl toreceive a number-bearing card 110, as clearly shown in Fig. 11, and eachof the said plates 107 is also provided with a short stud 111, whichIwhen the indicatordrop 106 is raised engages the upper edge of the wing104b to hold same to its elevated or indicating position. (See dottedlines, Fig. 6.)

To release the indicator-drops 106, I providel a pair of parallel rods112 113, which are secured to move in unison by clamps 114, and theupper one, 112, of said rods passes through bearing portions 104fof theend and middle bearings 104f, while the lower rod, 113, carries ahandle113x for moving the rod 113 into engagement with the lower end ofthe member 104b to release the drops 106. While the drops 106 are intheir non-indicating position, the lower edge of the indicating-plate107 of the drops rests upon the board 103", and to prevent lateralmovement of the drops 106 I fasten a collar106x at each side of thebearing portions 106 thereof.

Movable in bearings 115 on standards 116 is a rod 117, to one end ofwhich is secured an arm 118, carrying a friction-roller 118 at its freeend, which roller 118 is adapted to normally engage the cam 119,adjustably secured to the periphery of the motor-casing 11. Secured tothe rod 117 is a pair of downwardly projecting arms 120, connected attheir lower ends by an insulating-strip 120, upon which is secured atsuitable intervals a series of springs 120", which engage a series ofvertically-disposed spring-contact members 121, mounted upon the baseportion 122 of insulating material. the base 122 is a series ofcontact-plates 123, having portions with which the contacts 122 areadapted to coperate in the manner clearly Horiz'ontally secured toexplained by reference to Fig. 13 of the drawings. Y

One terminal, B, of each of the magneto-motor circuits `is connected toeach of the contacts 121, while the other terminal, C, connects with aseries of binding-posts 125. r1`he lineterminals from the alarm-boxes aconnect to the binding-posts 125 and 126, the post 126 being inelectrical connection with the contact-plates 123. (See diagram Fig.14.)

To one of the arms 48 I attach any suitable striker mechanism S, (shownin dotted lines in Fig. 6,) which may beof any approvedV type, since thesame forms no part of my present invention.

Operation: Assuming the parts to be in their nornal or inoperativepositions, as shown in Figs.1, 2, and 5, the cam 119 engaging the roller118, whereby all of the contacts 121 are held in engagement withk theircorresponding contacts 123, now if an operator desires to turn in analarm he sets in motion the.magneto-generator Gr in its box @whichenergizes its corresponding magneto-motor IOO IIO

MO at the alarm-station, causing its armature v -to reciprocate, andthereby through the action of the pawls 98 99 causing the ratchet-disk54 to rotate in the direction of the arrow in Fig. 5 until thestraddling-pawl 42 arrives at its vertical position, with itsfriction-wheel 44 in engagement with the number-wheel 40,

as shown in full lines in Fig.'6. As the lug 28 to become disengagedfrom the heel portion 22 of the weight 21, and thereby permit the saidweight 21 to drop (see dotted lines, Fig. 2) until its stud 24 engagesthe arm 69 on the shaft 65, and thereby overcome the tension of thespring 67, normally held in engagement with the lug 68, sufficiently toallow the arm 66 to become disengaged from the lug 88 of the disk 87 onthe governor-shaft 76 and set the machine in motion. To prevent theweight 21 dropping too far, I provide a stop or buer 150, as shown.Immediately after the machine is set in operation by the turning in ofan alarm the cam 119 will pass out of engagement with the roller 118 onthe arm 118 and allow the contacts V121 and 123 to separate, therebycutting' out all the alarm-circuits and preventing' any interference ofother alarms with the striking of the gong and the operating of themachine. As the motor-casing 11 revolves in the direction indicated bythe arrow motion will be imparted to the shaft 35, which rotates,carrying with it all the number-wheels 40. As only the pawl 42 of theparticular section of the machine set by the alarm is in engagement withits number-wheel, (see Fig. 6,) but one number will be struck upon theg'ong. As the number-wheel 40 revolves in the direction of the arrowfm., Fig. 6, the projections 41 on the wheel 40 will alternately raiseand lower the pawl 42, and consequently rock the arm 48. At the firstraise of the pawl 42 the linger 106 thereof will engage the under sideof the portion 106" of the drop 106 and raise the same to the positionshown in dotted lines in Fig. 6 until the stud 111 engages the upperedge of the wing 104, which holds the same with its number-face exposeduntil released by bringing the rod 113 into engagement with and locking'the member 104. The number of times the pawl 40 will be raised andlowered and the time relapsing between each raising' and lowering, andconsequently the frequency with which the arms 48 will be locked, willdepend upon the number and position of the projections 41 on therespective wheels 40 in engagement with the operative pawl 42, it being'understood that the number and arrangement of the number-wheelprojections are different for each number-wheel40. Now since the alarmturned in at the box has only served to set to the operative positionits respective section of the machine and as all the operating-circuitsof the system have been cut out it follows that the remaining sectionsof the machine willcontinue in their inoperative position, (shown inFig. 6;) but since all the pawls 42 are mounted upon the same rod 105when one of them moves up and down to rock the rods 48 all of the saidpawls will likewise move up and down in unison. Since only one pawl 42is in engagement with its number-wheel 40, the remaining number-wheels40 will not effect the movement of their re- P75eme spective pawls during the operation of the machine. Furthermore, to prevent theinoperative pawls 48-ff. e., those not in engagement with theirrespective number-wheels"- from setting their respective drops I providethe slots 106c in the portion 106h of the drops 106, so that the lingers106'1 of the inoperative pawls will pass through the said slots whilethe pawls are in the position shown in Fig. 6. Any suitable strikermechanism S (see dotted lines, Fig. 6) may be connected to one of thelever-arms, which will sound the alarm-gong in the usual manner. YInpractice the radii of the gears 34 and 34 are preferably such that thegear 34 will revolve three times to every revolution of the gear 34, so`that an alarm may be repeated a number of times before the mechanism isstopped.

Referring now more particularly to Figs. 2, 3, and 4, it will be seenthat as the motorcasing 11 revolves the lug 30 will engage the wing 23of the Weight 21, (see Fig. 3,) there by againfraising the weight,carrying it to and past its vertical position, as shown in dotted linesin Fig. 3, where it rests against a stop 130. lt must, however, beunderstood that l )efore the lug 3() engages. the wing 23 the lug 68upon the side wall 11h of the motor-casing 11 will become disengagedfrom the spring arm 67 on the shaft 65, so as to leave the arm 66 out ofengagement with the lug 88 on the disk 87. Since the weight 21 iscarried past its vertical position, its center of gravity will belocated between its fulcrum-point and the stop 130, and hence the weightwill remain in such position of its own accord. This is an essentialfeature of my invention, since the catch 28, lever-arm 55, and. shaft 50remain in the position shown in dotted lines in Fig. 2 and full lines inFig. 3 during nearly the entire revolution of the motor-casing. hereforethe heel 22 of the weight 2l would not engage the latch 28 were theweight permitted to drop. Now as soon as the lug 30 has moved through anangle of nearly three hundred and sixty degrees from its normal position(shown in Fig. 2) the saidlug will engage the under side of thelever-arm 55 and its cam 56, thereby raising' said arm 55 to rock theshaft 50, which in turn will cause the arm 60, through the medium of therod 61 and arm 27, to rock the shaft 26 to again bring the latch 28 toits weight-heelengaging position, as shown in Fig. 4. This rocking ofthe shaft 50 through the medium of the lever-arm 55 and lug 30 willcause the lingers 51 to engage the under pawls 99, which in turn engagethe upper pawls 98 to release them from engagement with the ratchet-disk54, which are then returned to their positions by the weights 54, andthereby disengag'e the operating-pawl 42 from its number-wheel 40. (Seedotted lines, Fig. 6.) As the motor-casing is completing its rotationthe lug 33 will engage the trip 32, causing' the pendent portion 31thereof to en- IOO IOS

TIO

gage the weight 21 and move it to its normal or catch-engaging position,as shown in Fig. 4. At the same time the cam 119 will engage the roller118EL of the arm 118, and thereby again close the contacts 121 againstthe contacts 123. As soon as the contacts 121 123 are again closed thelugA 68 will engage the spring-arms 67, thereby rocking the rods untilthe arm 66 engages the lug 88 on the disk 87, which stops the machine.By turning the crank 113x the drop may be released; As the spring-motorruns down the same may be wound up by attaching any suitable key (notshown) to the square portion 13b of the shaft 13 in the usual manner.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought the complete operationandadvantages of my invention will be'readily understood.

While I have shown but ten sections capable of setting ten drops andstriking ten different alarms, yet I desire it understood that I mayvary the number of sections as conveniences and circumstances mayrequire, and I further desire it understood that slight changes andmodifications of the construction and detail arrangement of parts of myinvention may be made without departing from the scope of the appendedclaims.
